# Time zones

**In a globalized world** you may have customers or potential customers anywhere on the planet, and you need to meet with them.

Many of the meetings, appointments or events you organize don't need a physical location. They can be **virtual** and take place on **videoconferencing platforms** such as [Zoom](https://www.tucalendi.com/en/s/integrations/integrate-zoom-in-tucalendi), [Google Meet](https://www.tucalendi.com/en/s/availability-configuration-events/connect-event-google-meet), [Microsoft Teams](https://www.tucalendi.com/en/s/integrations/integrate-microsoft-teams-tucalendi) or [GoToMeeting](https://www.tucalendi.com/en/s/integrations/integrate-gotomeeting-tucalendi).

Since there are **24 time zones** on Earth, it's important to keep in mind where you and your customers are located, so that there are no errors with each person's time zone when meetings are scheduled.

## Configure your time zone in TuCalendi

Once you [have registered in TuCalendi](https://account.tucalendi.com/login) and want to start setting up your account and scheduling your calendar and events, **one of your first steps should be to set your time zone**. This way, you'll see your events in your **local time zone** when you set them up, and it will be the reference whenever your clients or customers schedule a meeting or event with you. You can **change your time zone** at any time.

## How TuCalendi detects the time zone of your users or customers

**TuCalendi automatically detects the time zone** of the clients or customers who are going to book with you. It then **adjusts the event availability** to the customers' local time, avoiding errors caused by the **time difference**.
